roundcube - 收件箱列表为空 - the list is empty - imap - vsz_limit 256 MB

现象：某个邮箱用户登录到 roundcube webmail，收件箱列表是空的。原先的邮件数约有十万封。

实践：查看 dovecot 的 imap.log ，出现类似 (Out of memory (service imap { vsz_limit=256 MB }, you may need to increase it)) 的字样。按网上的例子，在 /etc/dovecot/dovecot.conf 添加如下内容后，重启 dovecot 服务即可。

service imap {
  vsz_limit = 1024MB
}

在“抖音商城”里买“玉米鲜肉云吞”

我用电脑的时间多，用手机的少。“抖音”app是前阵子在网友力荐下才安装的。每天我习惯地在“抖音”点签到，然后领三角钱。

今天，“抖音”app播放的视频是“袁小铰”的直播间，显示18个玉米鲜肉云吞卖6.8元，叠加新人支付优惠后只要2.8元。犹豫了一下，觉得有便宜得占，我就提交订单了。订单显示30天内可凭二维码到实体店里核销提单。

十一点多时，我到了在果园的实体店。店里的人告诉我“抖音”的订单需要到店外的玻璃窗口里处理。我走到店外，里边有个工作人员拿着个手机让我出示二维码。之后，她问我是不是各种馅都各拿几个。我说“好”。

菜名：6.8元抢18颗玉米鲜肉云吞
门店：果园市场附近的“袁小饺”店
份量：约半市斤，够大人食一餐
口感：可能因为夹杂了韭菜、紫菜、香菇猪肉馅，所以连吃18颗，不会觉得腻
评价：可以试一下，适合一个人懒得整饭食的

无法为 FreeBSD 9.3 Release 的 vm-images 打上阿里云的 VirtIO 补丁

问题描述：无法为 FreeBSD 9.3 Release 的 vm-images 打上阿里云的 VirtIO 补丁。因为业务问题，须使用 FreeBSD 9.3 amd64 系统。我先从 http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/old-releases/VM-IMAGES/9.3-RELEASE/amd64/Latest/FreeBSD-9.3-RELEASE-amd64-20140711-r268512.vhd.xz 下载系统镜像。再按照 https://help.aliyun.com/zh/ecs/user-guide/the-freebsd-operating-system-compatibility 这里的操作说明，想为内核打上 0001-virtio.patch 的补丁。但在执行 make -j2 buildkernel KERNCONF=GENERIC 这一步时，出错。提示：cc1: warnings being treated as errors . * [virtio_pci.o] Error code 1

阿里云客服回复：实在抱歉，FreeBSD 9.3 这个系统太老了 ，这边尝试多种方法也找不到的virtio驱动，只能建议您更换其他操作系统进行使用了，谢谢

客户反馈腾讯云的可以安装 FreeBSD 9.3 。

在 apache 里设置 acme 验证证书的目录

如这里提到的：https://doc.owncloud.com/server/next/admin_manual/installation/letsencrypt/apache.html

我拿来套用的例子：

  <Directory "/var/www/acme/.well-known/acme-challenge/">
      Options None
      AllowOverride None
      ForceType text/plain
      RedirectMatch 404 "^(?!/\.well-known/acme-challenge/[\w-]{43}$)"
  </Directory>

 SSLEngine on
 SSLCertificateFile  /root/.acme.sh/demo.anqun.org_ecc/demo.anqun.org.cer
 SSLCertificateKeyFile /root/.acme.sh/demo.anqun.org_ecc/demo.anqun.org.key
 SSLCertificateChainFile  /root/.acme.sh/demo.anqun.org_ecc/ca.cer

</VirtualHost>

<VirtualHost *:80>
  ServerName demo.anqun.org
  Redirect permanent / https://demo.anqun.org/
